Hey, I am having the same issue and I will alabrate on this. 1. I am on macOS high sierra 2. Previously I have attempted to run Roblox on my virtual machine but failed as it was too laggy. 3. one day I attempted to log onto Roblox using my mac like normal when suddenly it started redirecting me to my windows 10 virtual machine to play. 4. I kept trying to get it to use my macOS original copy of Roblox but it would not stop so I just deleted parallels desktop at once. 5. It then was saying parallels desktop could not load this app. (example provided in the first comment on this forum) 6. I then read threw all of the comments and deleted the windows applications folder and it still did not work 7. I then started to go threw finder to try and delete everything that has to do with parallels desktop 8. and it still does not work and now I am writing a comment to try and get some help 9. my only idea of fixing this now is to erase my hole computer... Please help.
